4237 /* Notes:
4238  *   add / delete: all types that may be added or deleted must use an
4239  * X-ORDERED attributeType for their RDN. Adding and deleting entries
4240  * should automatically renumber the index of any siblings as needed,
4241  * so that no gaps in the numbering sequence exist after the add/delete
4242  * is completed.
4243  *   What can be added:
4244  *     schema objects
4245  *     backend objects for backend-specific config directives
4246  *     database objects
4247  *     overlay objects
4248  *
4249  *   delete: probably no support this time around.
4250  *
4251  *   modrdn: generally not done. Will be invoked automatically by add/
4252  * delete to update numbering sequence. Perform as an explicit operation
4253  * so that the renumbering effect may be replicated. Subtree rename must
4254  * be supported, since renumbering a database will affect all its child
4255  * overlays.
4256  *
4257  *  modify: must be fully supported.
